Chemistry teachers -– especially those who work alone –- may enjoy using these videos just to hear another instructor’s musings, or as a way to review advanced queries and responses from knowledgeable users. For students, however, most of the material here could make an already challenging topic more difficult due to the advanced language and unpolished presentation. Nevertheless, the videos are conceptually correct and cover all the major chemistry topics. Better interactivity would help the lessons reach more kids. For most of the material, you can use these chemistry lessons as an enrichment option for students. And definitely send your kids with intriguing inquiries here. Perusing the community blog can be a great way to feed a curious mind.
For most students, these lessons are probably best used in a flipped-class scenario. Have them view a video first, and then use their notes, outlines, or questions to start class discussions. Alternatively, you can encourage kids to use the lectures as a review. Most students will need clear guides, note-taking instructions, or other means of scaffolding to help them process some of the more complex topics. As an exception, the stoichiometry practice problems are a great resource on their own. There are seemingly endless versions for practice, and the step-by-step hints allow most users to avoid frustration. During class, have students hop on for 5-10 minutes to sharpen their skills while you check in with individuals.

Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium.
Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
